Abstract
Purpose – The purpose of this chapter is to consider the historical context of the gradual release model as it emerged following the early twentieth century emphasis on behaviorism as psychologists (and reading researchers) increasingly focused on cognition in the reading process. This “cognitive turn” in educational psychology was followed closely by a “social turn” with its focus on the socially constructed nature of texts, learning, and reading, particularly influenced by Vygotsky and work on scaffolding.
Design/methodology/approach – This chapter uses literature from the field to contextualize the gradual release of responsibility (GRR) model and to discuss research or practice chapters included in this edited volume.
Findings – This chapter described the transition from behaviorism to cognition to social construction as it applies to the reading process generally and to GRR in particular. It noted that this transition has required teachers to be more nimble and flexible than ever before, cautioned that the complexity of classroom life and the pressures on teachers can cause techniques such as GRR to be misused, and suggested ways to manage the group work which is central to social cultural approaches to literacy. And along the way it spotlighted the ever-widening range of applications of the GRR documented in the earlier chapters of the book.
Practical implications – The section in this chapter with most immediate practical implication is clearly the section on misuses of the GRR model. This section discusses some misuses of the model: neglecting explicit teaching; missing the middle (i.e., jump from explicit teaching directly to independent practice); and applying in an overly rigid manner.
Originality/value of paper – This chapter makes an original contribution to the field in providing a historical context for the gradual release model and for addressing the chapters in this edited collection. The authors also point to some areas for next steps forward as reminders to those applying the model.

Abstract
Introduces the need for engineering knowledge management tools for storing past solutions and expert knowledge for the design of automatic precision machinery. The design of this type of machine, which is heavily utilised in modern manufacturing industry, is very complex, time‐consuming and potentially expensive. Describes the design and functionality of a novel computer aided rapid prototyping tool named Schemebuilder. The design is traced from its philosophical origins in the “Theory of domains” and how this can be used by the designer with the aid of the computer. The application of this underlining methodology for the design of precision machinery employing feedback control systems is also described. Finally an example is shown for the design of a control system for precise position control of a glass bottle making machine.

Abstract
Purpose
This paper aims to, using a unique loan-level data set, show the extent to which negative equity in Ireland is concentrated in younger age groups. The sharp decline in house prices since 2007 has led to the emergence of widespread negative equity in Ireland. However, little is known about the type of borrower experiencing negative equity.
Design/methodology/approach
This paper uses a unique data set that, for a large sample of mortgages, provides details on both the characteristics of the borrowers and their mortgages. Using this data set, the paper estimates the incidence of negative equity by analysing loans taken out to purchase a primary residence in the period 2005-2012.
Findings
The analysis finds the situation in Ireland to be much more severe than that being experienced in other housing market downturns at present, with 64 per cent of borrowers in the period 2005-2012 experiencing negative equity. Analysis by age gives rise to concern, with the majority of those in negative equity aged under 40 years. The paper also points to the large wealth loss experienced by Irish households, in the order of 43 billion, as a result of the fall in property values.
Originality/value
The paper is one of the first using loan-level time-series data in Ireland. It highlights the growth in negative equity during the crisis and the extent to which it is concentrated in the younger age groups. It also provides an estimate of the loss in wealth suffered by all households due to the fall in Irish house prices.

Abstract
In his review of 30 years of research in Prospect Theory, Barberis (2013) notes that support for Prospect Theory had come mainly from the laboratory. In this paper, I write about a recurring phenomenon in real life that is consistent with Prospect Theory predictions in decision-making loss domain. The 60 cases noted in this paper are associated with specific risk seekers that had cost more than $140 billion (an average of $2.33 billion per case). Given space consider– ations, I provide synopses for 14 cases. A few of these cases have been discussed in the extant literature in connection with internal control, but were not considered from the perspective of Prospect Theory. It is striking that these cases are costly, all participants are young men, and almost all had followed the gambler’s martingale strategy – i.e., double down. While these cases are informative about risk-seeking behavior, they are not sufficiently systematic to be subjected to stylized archival research methods.

Abstract
This study finds evidence that a stock return is inversely correlated with downside risk, confirming a pattern of risk-aversion behavior. Evidence from testing a stock return's response to a change in economic policy uncertainty indicates a significantly negative effect in the Chinese stock market; this conclusion holds true for testing the impacts of changes in fiscal and monetary policy uncertainties. However, the data produce a mixed effect for the change in fiscal policy uncertainty. The evidence produced from examining the geopolitical effect on the stock market strongly supports the presence of an adverse effect on stock market performance.
